BAILEY M. FENNELI, OF CRIS'ITOQTACITVAI ZOE'E, ASSIGNOROF ONE-HALF TOJAMES A. SMITH, OF BRISTOL, TENNESSEE.

To all whom it may concern.'

Be it known thatI, BAILEY M. FENNELL,

`a citizen of the United States, residing at Cristobal, Canal Zone,Panama, have invented certain new and useful Improvements in Envelops;and I do hereby declare the following to be a full, clear, and exactldescription of the invention, such as will in means is provided fordisclosing upon the face of the envelop a plurality of surfaces adaptedto receive addresses.

A further object lies in the provision of sucha device which will beefficient in use and shall yet possess such a simple design as to permitready and economical manufacture.

Vith these and other objects in view, the inventiony resides in thenovel combination, forma-tion and arrangement of parts more fullydescribed in the following specification and particularly pointed out inthe appended claim.

Reference is had to the accompanying drawings, wherein similarcharacters of referencey designate corresponding parts throughout theseveral views and in which:

Figure 1 is a front elevation of an envelop vwith my device appliedthereto. Fig. 2 is a rear elevation of the envelop with the back thereofbroken away to more fully disclose the invention. Fig. 8 is a section onthe line 3-3 of Fig. v1, and Fig. 4 is a blank from which the addressslip is formed.

Referring tothe drawings, 10 designates a usual envelop to which isapplied a preferred form of the invention. The envelop is pro vided onits face 11 with a pair of spaced parallel longitudinally extendingslits 12.

An address slip 13 isl provided substantially rectangular in shape andhaving its upper end 14 tapered to a point. This address slip is trainedthrough the slits from the interlor of the envelop so that by slidingthe slip through the slits a fresh surface is Copies of this patent maybe obtained for Specification of Letters Patent.

provided on the face of the envelop. To prevent withdrawal of the bottomof the slip through the slits there is provided on the lower extremityof the slip a pair of lateral extensions l5. These extensions bearagainst the ends of the lower slit and perform the function abovementioned.

To protect the slip a shield 16 is provided, which is substantially thewidth of the en velop and which is secured at each side to the innersurface of the face thereof. The address Slip, when in its lowerposition, is bent over the shield on the dotted line 17. When theaddress slip is positioned in its raised position, it is bent over thetop of the shield on the line 18.

. When the envelop is mailed the address slip is in its lower positionand the address of the receiver is written on the surface thereofexposed between the slits 12. When it is desired to readdress theenvelop, the address slip is raised and bent down on the line 18, thusproviding an entire fresh addressing surface.

It is thus seen that an exceedingly simple device is provided which willperform all of the functions desired in a highly satisfactory manner.

That is claimed is:

The combination with an envelop provided with a pair of longitudinallyspaced parallel slits in its face, of an addressed slip substantiallyrectangular in shape and slidably trained through the slits and adaptedto contain a pair of addresses to selectively expose one, a pair oflateral extensions on the bottom of the slip forming stops to limit thesliding movement of the slip in the slits and a shield provided adjacentthe inner sides of the face of the envelop and secured thereto, saidshield being substantially of ve cents each, by addressing theCommissioner of Patents, Washington, D. C.
